I'm trying to display small image inside devexpress grid.
My controller return an image file to my view which is fine(please do not advise me to store image path in my db instead file itself, this is not the question here) to continue I'm getting image in my view calling
Url.Action("GetImage", "Property", new {id = image.Id })
Thats working fine except in devexpress gridview.
If anyone have expirience with DevExpressHelper.WriteToResponse() and know how to use it to properly render <img width="50" height="50" src="/Property/GetImage/5" alt=""> inside devexpress gridview please share.
Thanks
The DevExpressHelper.WriteToResponse method seems to be obsolete.
I believe you can use the approach suggested in the http://www.devexpress.com/issue=Q313518 DX KB as a starting point.
The grid supports templates. One template type is for styles.
Have a look at this demo:
http://demos.devexpress.com/MVC/GridView/Templates
For ASP.NET WebForms you could look here
http://demos.devexpress.com/ASPxGridViewDemos/Templates/Template.aspx
Edit: Provided WebForms demo, when a MVC demo would have appropriate

I am using ASP.NET MVC with Kendo UI. I want to export grid to an HTML page and print it. Online help is not available. What have your done previously. Thanks in advance.
Did you find a solution to this? I'm looking at the same thing currently and have found a couple of options:
Firstly Telerik have a Javascript example which renders your grid to a new print window, see https://docs.telerik.com/kendo-ui/controls/data-management/grid/print-export
Just alter the name of
var gridElement = $('#grid'),
to your own existing grid name and omit the function:
$(function () {
var grid = $('#grid').kendoGrid({
...
};
};
However, this only renders what is currently displayed on screen (so if your grid has multi pages it may not be suitable).
The second option that I'm exploring is exporting to pdf (and then user can then print that if they wish). There are example of this at
https://demos.telerik.com/aspnet-mvc/grid/pdf-export and https://docs.telerik.com/kendo-ui/controls/data-management/grid/pdf-export
This does have multi-page printing support (although I haven't got it to work just yet, they have examples which show it working). They do mention potential problems if you have a lot of data as it needs to load all the data on the client side (even if you have paging). There are some example projects to work on data server side in the above links.
In the end our requirements didn't need the paging but I've gone with the pdf option as that delivers quite a nice layout that you can template further.
I want to display file on my form using MVC.
I am bringing a Byte[] array data from the Database, and using FileContentResult I am converting it into a file.I want to now display this file on my page for viewing . How can it be acheived. What code to write in my View for the same.
Assuming you're using Razor, rendering a text file can be done as simple as:
<div>
#(new System.IO.StreamReader("myFile.txt")).ReadToEnd()
</div>
For PDF files, you'll have to find a third-party component to convert to HTML.
You probably don't want to use FileContentResult, that is something generally used for providing the raw file.
In theory though there is nothing different in using any other url
<img src="#Html.ActionLink("View","Image",{id = Model.key})" />
Or you can provide that link in a pdf reference, or as a stylesheet etc.
I am new to MVC . I am creating a bookstore webpage application using aspx, and mvc. I have a database of books that says available or sold out. When a user clicks a dropdownlist they choose a book, it shows an image next to the book that is either supposed to show a green check mark if it is available or a red X if its not available. That information is all pulled from a database. My question is how do I change the image once a book becomes available. By the way my images are stored in my Content folder under imgs.
I have been searching for a while and haven't found a good answer. Any help or any websites you can suggest would be great thanks.
My image says this
<asp: Image ID = "Book_Availability" runat = "server" />
-----------Update----
When I mean change, I mean change the ImageURL so that it points to a different picture. On the server side I have value of 0 or 1. When I get a 1 i want to update the image URL to point to a different ImageURL from the controller, so that its from a X to a check mark. I am not sure how to accomplish this using MVC
Check out this link on Razor syntax. You could achieve what describe with something like:
#{
string availableImage = Url.Content("~/Images/availableImage");
string unavailableImage = Url.Content("~/Images/unavailableImage");
}
<img src= "#(Model.IsAvailable ? availableImage : unavailableImage)" alt="" />
You could perhaps add an click event handler onto the dropdown using jQuery. This could in turn do a $("#myimagewrapperexample").load() event against an action on some controller i.e BooksController
The action could return a partial view containing the books current image for example. Or it could return true, false depending on the books availability and you toggle the image in your javascript. All the action would need to be passed would be the id of the book and you could then look it up to determine it's status.
I've never used asp tags in a MVC project so can't comment on your usage there. AlexC suggestion of looking into the Razor syntax if your using MVC 3 is a good idea. Otherwise you might want to look into creating views using MVC 2. This Microsoft link might help you out on that front.
I have following code
#Html.Pager((IPagination)Model.FoundUsers).Last("<span class=\"last\"> </span>").First("<span class=\"first\"> </span>").Next("<span class=\"next\"> </span>").Previous("<span class=\"prev\"> </span>")
But it renders encoded and shows <span class="next"> on page.
I tried to used Html.Raw as suggested in Problem with razor view and mvccontrib grid pagination or How to make a pager with MVCContrib and Razor?
but it still does not work for me.
What am I doing wrong ?
I would assume that you are using MvcContrib v2 with Mvc4 (or possibly Mvc3)?
Either manually download the newer libraries from http://mvccontrib.codeplex.com or use the Raw method. So instead of this:
#Html.Pager((IPagination)Model.FoundUsers).Last("<span class=\"last\"> </span>").First("<span class=\"first\"> </span>").Next("<span class=\"next\"> </span>").Previous("<span class=\"prev\"> </span>")
You would instead have:
#Html.Raw(Html.Pager((IPagination)Model.FoundUsers).Last("<span class=\"last\"> </span>").First("<span class=\"first\"> </span>").Next("<span class=\"next\"> </span>").Previous("<span class=\"prev\"> </span>"))
Perhaps it's because I am working in VB, but I had to get the appropriate string from the Pager object:
#Html.Raw(Html.Pager(Model).ToString)
I'm using MvcContrib 2.0.95 with MVC 3.
We have a bit big blocks of C# code within our cshtml files which must be presented in cshtml and nowhere else (obviously it's not a brilliant case but it's another question).
How we can collapse or hide these blocks of code in order to let our designers work more smoothly? We also want to hide these blocks of code during the demos of the progress with markup.
The real issue is that we also must save the visual representation into SVN.
Is there any native VS 2010 functionality for this or plugin? Maybe there is an opportunity to use "partial" cshtml pages where all the markup will be in one file and all C# code will be in another?
Unfortunately VS isn't going to collapse C# blocks of code within #region directive in such files.
Ultimately there is a similar question Regions In ASP.NET Views? but it gives no answer on how to save the collapsed representation when "Collapse Tag" context menu action item was used.
Try using Visual Studio's collapse functionality. By default I believe the keys are:
[Ctrl+M,Ctrl+H] to hide an arbitrary selection, and
[Ctrl+M,Ctrl+U] to unhide the same ( while collapsed ).
This should allow you to temporarily hide any code. More details available on MSDN
Is this what you were looking for?
Having read a little further you wish to save them collapsed, and apparently .cshtml doesn't support #regions. I guess a hacky solution might be the old:
#if(false){
<div>
<!--/*{your long code}*/-->
</div>
}
Or something to that effect, but you get the idea :)
Just select your code, right click and select Collapse Tag
The way that I see it is that cshtml files are meant for a "user control" side of a presentation layer. If you have too much code in your view files, then I would refactor the code and move re-usable components into partial views. I would then include these partial views through
#Html.RenderPartial("PartialViewName", Model.propertyToRender), or I would use
#{ Html.RenderAction("ActionName", "ControllerName") ;}
